SHUTTLE-TONGUE FOR SECURINGVAND HOLDING THE COP v0F VVOOE."v

Speccation of Letters Patent No. 162, dated April 17, 183:7.

To all whom t may concern: Y

Be it known that I, COMFORT B. THORP, of Smithfield, inthe county of Providence and State of Rhode Island, have invented a new and improved mode of more ett'ectually securing and holding the cop of Woof upon the tongues of the common power loom shuttles than the mode now in use, preventing the cops of woof from sliding olf from the tongues while weaving, especially the last part of them, which so frequently slips from the common smooth tongues and is drawn into the web, injuring the cloth and wasting yarn. p

My improvement consists of ridges, or parts jutting from the surface of said tongues, protruding into the cop, against which the innermost turns or coils of the woof will lodge, and prevent the cops sliding from the tongues. There `are various ways to form or produce said projectures or protuberances, such as cutting long notches in the corners of a square tongue, leaving the prominenoes extending out the full size of the square resembling in some degree the tooth of a saw, the point or cutting part of which will stand toward the heel or pivot of the tongue, and about ve-eights of an inch apart on each corner and so arranged that neither of them will come opposite of The most convenient way to form and use the Y improvement on the common Vsmooth round tongue, will be towind a piece. of

wire around it, spirally, beginning at the head of the tongue near its pivot, and forming about eight turns more or less onward toward its point, each turn'should be threeeighths of an inch apart or thereabout. The wire should be the sixteenth of an inch in diameter, though it may vary from that size and conned to the tongue by solder or byv The above described projectures whose' prominences protrude into the cop for the purpose of more eectually securing `and holding the cop of woof on upon said tongues. Also the application of the worm,

or the spiral projecting lip or edge tothe round tongue as herein described for the purpose of holding and preventing the copV from slipping olf from the tongues of the shuttles while weaving.
